Essential Career Information

The broad field of physical science encompasses professions such as atmospheric scientist, chemist, environmental scientist, geoscientist and physicist. Job duties vary, but virtually all physical scientists work with non-living materials. Using the scientific method, they perform experiments and draw conclusions. Atmospheric scientists (often called meteorologists) study climate and weather to develop forecasts. Chemists study materials at the molecular level. Environmental scientists devise ways to clean and preserve the environment. Geoscientists study the earth to find sources of energy, minerals and water. Physicists study the physical properties of matter that includes everything in the earth and universe.

Job Description

In general, physical scientists investigate and study the composition and structure of matter, from the smallest atom to the planets of the universe. All physical scientists may teach, plan, test, research and develop scientific studies to test physical properties. Physical scientists usually work for colleges or universities, the government, hospitals and research companies.

Employment Outlook

According to the BLS, the job growth for chemists was projected have a 6% increase from 2012-2022, which is slower than average. Although employment of chemists was expected to decline in the chemical and drug manufacturing industry, the BLS expected increasing opportunities for chemists in the environmental industry. During this same period, job growth was projected to be about average for atmospheric scientists (projected to increase 10%), environmental scientists (15% increase) and physicists (10% increase).

Some favorable factors contributing to the job growth for these professionals are due to the demand for more accurate weather forecasts, concern for the environment as the population grows and the expected increase in government spending for energy. The BLS also noted that jobs for meteorologists were expected to be very competitive because there are usually more candidates than there are jobs. As for geoscientists, jobs were projected to increase 16% between 2012 and 2022, which is faster than average. This growth projection was based on the anticipated demand for energy sources and more efficient ways to protect the environment. For all of these positions, job prospects were expected to be favorable for those with advanced degrees, especially for those with a Ph.D.
